Prove this analysis is incorrect.
"The reason that increasing renewable generation leads to accelerating consumer prices is that an electrical grid must operate with one hundred percent reliability on a 24/7/365 basis. A reliable grid requires a very close match between power supplied and power demanded on a minute-by-minute, and even a fraction of second, basis. But wind and solar sources experience large, unpredictable, and often sudden swings in the power that they supply. Therefore, in a grid using large amounts of power from wind and solar sources, additional costly elements must be added to the system to even out the supply and always match it to the demand. These additional elements are what bring about the increased costs and thus increased consumer prices:
[T]here will be substantial times when no such power is available (e.g., calm nights). Therefore, all or nearly all pre-existing fossil fuel capacity must be maintained, even though some of it may be idle much of the time. Although the fuel cost of the renewables is zero, the operator must pay the capital cost of two overlapping and duplicative systems to the extent of the renewable capacity."
